In case anyone's interested, here's what I use for my custom error handler:
function __debug_error_handler($type, $msg, $file, $line, $context) {
if (ini_get('html_errors')) {
$hr = '<HR>';
$br = '<BR>';
$nbsp = ' ';
$b = '<B>';
$slash_b = '</B>';
} else {
$hr = "-----------------------\n";
$br = '';
$nbsp = ' ';
$b = '';
$slash_b = '';
}
echo $hr . ini_get('error_prepend_string');
$list = Array(E_USER_ERROR => 'U_ERROR',
E_USER_WARNING => 'U_WARNING',
E_USER_NOTICE => 'U_NOTICE',
E_ERROR => 'ERROR',
E_WARNING => 'WARNING',
E_NOTICE => 'NOTICE');
if (array_key_exists($type, $list)) {
$type = $list[$type];
} else {
$type = "UNKNOWN ERROR CODE ($type)";
}
echo "$b$type:$slash_b $msg$br\n";
$bt = debug_backtrace();
$from = '';
for ($i = 1; $i < count($bt); ++$i) {
$step = $bt[$i];
$class = isset($step['class']) ? $step['class'] . '::' : '';
if (empty($step['file']))
$step['file'] = '';
if (empty($step['line']))
$step['line'] = '';
printf("$nbsp$nbsp %s$b%s%s$slash_b [%s:%s]$br\n",
$from,
$class,
$step['function'],
$step['file'],
$step['line']
);
$from = "$nbsp$nbsp$nbsp$nbsp from ";
}
echo ini_get('error_append_string');
} // __debug_error_handler
